**Description:**
This PR introduces a major overhaul of how streams are analyzed and connections are managed. It integrates `ffprobe` for deep stream analysis, adds a background task queue for metadata resolution to prevent UI blocking, introduces a connection priority system, and adds support for Live TV probing.
### 🚀 Key Features
* **FFprobe Integration & Live TV Probing**:
* Automatically probes streams (VOD/Series **and now Live TV**) to determine resolution, codecs (HEVC/AV1), dynamic range (HDR/DV), bit depth, and audio channels.
* **Safe Probing**: Probing strictly respects the provider's `max_connections` limit.
* Docker images now include static `ffmpeg/ffprobe` binaries.
* **Smart Connection Management (Priority System)**:
* Introduced a priority system for connections to manage provider limits intelligently.
* **Preemption**: Users with higher priority can preempt (kick) lower priority connections when provider slots are full.
* **Background Queue**: Metadata resolution and stream analysis run as background tasks (Priority 0). They only run when connection slots are idle and yield immediately if a real user needs to stream.
* **Enhanced Metadata Resolution**:
* **Fallback Logic**: If a provider is missing the TMDB ID or Release Date, the system resolves them via the TMDB API.
* **Smart Title Cleaning**: Implemented a centralized cleaner to strip common IPTV prefixes before attempting metadata matches or generating filenames, significantly improving match rates.
* **Improved Output**:
* **Quality Tags**: Filenames in STRM files now include detailed tags (e.g., `Movie - [4K HEVC HDR].strm`).
* **Flat Grouping**: `flat: true` now correctly groups multi-version movies into single folders based on TMDB ID.
* **Global Series Date**: Ensures consistent series folder naming even if episodes have different years.
New Features
- Automatic provider failover & rotation across multiple provider URLs with a provider:// scheme and capped retries
- Configurable failover redirect patterns to influence retry/failover behavior
UI
- New interface to view and edit failover redirect patterns in reverse proxy configuration
- Expanded docs covering Provider Failover & Rotation and enriched messaging templating
Reliability
- Improved URL resolution, error reporting and logging for more robust provider handling
B+ tree now supports a multi-block layout to handle records that exceed a single block.
Additionally, a larger safety factor was added to the overhead calculation to reduce the risk of data overflow.
Added in-place update for values if they fit in the block without rewriting the whole tree structure.
Implemented an LRU Block Cache (Node Cache) for the query engine.
Implemented zero copy key lookup
Added --dbv for printing id_mapping.db files
Increased initial load time with mmap
Release process now includes validation to confirm that release notes are present before deployment can proceed; if release notes are missing, the release process will terminate with an error message
Release workflow now requires an interactive confirmation step during the release process; explicit user approval is mandatory before any release actions commence
* Season Order fix

* cargo clippy fixes
* Fixed series sort issues
* Playlist explorer copy to clipboard functons implemented
* Epg time fix
* grace period hold stream option added.
* Fixed group and mapper normalization
* Image cache validity for browsers set to 4 hours. Responding now last modified and cache header.
